Identifying and proving the who value, that is, who is the initiating entity, is usually...

The correct answer is B. False . In Zero Trust architecture, identifying and validating who is making a request is normally handled through enterprise identity systems , not by a government agency. Zscaler’s authentication architecture explains that authentication credentials and identity responses from an Identity Provider (IdP) are the first step in determining which policies should apply. Those responses can include the user’s identity, groups, and department, which are then used in policy enforcement.

ZPA guidance also shows that SAML and SCIM attributes from the identity provider are used to support application access policy. This means the “who” value is typically proven through the organization’s identity stack, such as an IdP, directory service, or integrated authentication platform, not through an external government authority.

While government-issued identity documents may be part of a hiring or registration process in some organizations, that is not how Zero Trust runtime identity verification is generally performed. In practice, the “who” is established through enterprise-controlled authentication and context systems. Therefore, the statement is false.
